JAMES C. I. VILSON, OF CHICAGO, ILLINOIS.

COPY-HOLDER.

SPECIFICATION forming part of Letters Patent No. 598,689, dated February8, 1898 Application filed March 3l, 1897.

To a/ZZ whom t may concer-m Be it known that I, J AMES C. I. WILSON, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inType-Vriter Copy-Holders, of which the following is a specification.

My invention relates to an improvement in the class of copy-holderscarried by jointed brackets, through the medium of which they areadapted to be attached to type-writing machines and swung thereon fortheir adjustment to different positions.

More particularly stated, my invention in the class of copy-holdersreferred to relates to improvement of the features of the springclampfor holding the copy (book or sheet) and a leaf-clamp adjunct.

The accompanying drawing shows my irnprovement by a perspective view asoperatively applied to a type-'writing machine, of which abroken portionis represented.

A is the support for the copy, which I prefer to form of theconstruction illustrated. The construction shown of the support A is asfollows: From the opposite ends of the rear edge of a ledge r thereproject upward the single sockets r and r2, and from the same edge,at apoint midway between the end sockets, there projects upward the doublesocket frs. An adequately stiff Wire p is bent upon itself into theshape of a rectangle to form one half of Vthe back of the support, withone end fastened in the socket r/ and the other end fastened in one ofthe holes of the socket r3, and the length of this wire forming a sideof the support is bent near its upper end to form a laterally openbearing-loop o for a purpose hereinafter described. A similarly-bentwire 4o p forms the other half of the support by having one end fastenedin the socket?12 and the strips p2 and p3, which may be formed of thinSerial No. 630,142. (No model.)

sheet metal. The parts p, p, p2, and p3 thus form the back of thecopy-support.

B is a clamp which may be formed out of a single length of adequatelystid wire,atford ing the straight rod portion n or back of the clamp, atwhich it is journaled in the loops o and o', the handle n, by which tomanipulate the clamp, the forwardly-bulging vertical shoulders 71,271.2,and the clamping-arms n3 n3, extending toward each other from the lowerends of the shoulders along the reinforcingstrip p2, but short of thecenter thereof to leave them separated by a space m between their ends.A spring Z, connecting the clamp with the support A, as shown orotherwise, imparts to it yieldingly its clamping function, in performingwhich against the matter to be held, which is inserted for the purposebetween the clamp B and the back of the copysupport A, the clamp forms aspecies of springjaw cooperating with the back of the support, whichforms, as it were, a stationary jaw. By providing thisvertically-swinging clamp with the separated clamping ends a copy-bookwhich opens along its shorter edge and one opening along its narroweredge may be adjusted with equal facility in the clamp through the spacem, and the holding effect of the clamp is enhanced by the bulgingconstruction of the shoulders n2.

B is a resilient leaf-holding adjunct of the clamp, shown as formed ofalength of springy wire bent upon itself to afford the arms i and i',connected by a back 2, at which the device is journaled in the loops o2and o3, being sustained by a stop 5, and the arm 1l' extends at the backof the strip p2, with which it is connected, and the arm extends aboveand along the top of the support in position to stop from flying back aleaf or the section of `a book turned over the top of the support.

To permit turning a book-leaf 4over the top of the support,` the wire ishould first be turned backward out of the way'and released to fly backafter the leaf has been adjusted to obstruct or hold it againstreturning.

C is the supporting-bracket for the support A. It may comprise anydesired number of sections jointed together to swing horizontally. Asshown, the bracket is formed with four sections It, h', h2, and h3. Thesection h has a rigid claw f at one end, at which it fits over a lowerside bar o of the frame of a type-writing machine D and upon which it isfastened by a thumb-screw f, and on the other end 'of this section is asocket g to receive the pintle e on one end of the Z-shaped section h',the opposite end of which contains a socket g to receive the pintle e onone end of the L-shaped section h2, the opposite end of which isconnected pivotally with the Vertically-opening eye cl on one end of thesection h3, having a horizontally projecting threaded stem CZ at itsopposite end. The connection of the bracketC with the support A is madeat the stem d on the section h3 by passing the stein through ahorizontal opening in the lug c, projecting from the center of the rearedge of the ledge r, and clamping the parts together by means of athumb-nut c', applied to the stem against a washer c2 thereon.

- By the described connection of the jointed bracket with the support Awhen the device is attached to the machine D with the supportoverhanging the latter the supportv may be turned down on loosening thethumb-nut c' to lie flat against the top of the machine 4and thus letthe desk containing it be closed in the usual manner without obstructionfrom the copy-holder, which need not be detached, since it drops withthe type-writing machine in closing the latter and is brought intoposition for use upon raising the supportA on the stem d when themachineis raised by opening the desk.

What I claim as new, and desire to secure by Letters Patent, is

1. In a copy-holder for type-Writing machines, the combination of acopy-support, a clamp hinged to said support to swing up and downthereon with relation to its front side and terminating in clamping-armsextending toward each other from opposite sides of the center'of saidsupport and separated at their ends to afford between them acopy-insertion space, and a spring connecting said clamp with saidsupport, the spring-controlled clamp and back of the support formingjaws coperating to hold the copy inserted between them, substantially asdescribed.

2. In a copy-holder for type-Writing machines, the combination of acopy-.support having laterally-open bearing-loops in its opposite sidesnear its upper end, a clamp comprising the rod n journaled in said loopsand having a handle at one end, shoulders n at its opposite ends andarms n3 extending toward each other across the face of said support andforming between them the copy-insertion space m, and a spring connectingsaid clamp with said support,the spring-controlled clamp and back of thesupport forming jaws cooperating to hold the copy inserted between them,substantially as described.

3. In a copy-holder for type-writing machines, the combination of acopy-support having laterally-open bearing-loops in its opposite sidesand in one side vertically-open bearing-loops, a spring-controlled clampB comprising the rod n, j ournaled in said laterally-open loops, ahandle at one end of said rod and shoulders'n,2 at its opposite endsterminating in arms n3 extending toward each other across the face ofsaid support and forming between them the copyinsertion space m, and aspring-controlled leaf-holder B journaled in said vertically-open loopsand having an arm extending along the top of said support, substantiallyas described.

4. In a copy-holder for type-Writing machines, the combination of acopy-support A comprising the ledge r and back thereon formed of thebent wire p containing the loop o, the bent wire p containing the loopoand the reinforcing-strips crossing said Wires, and a spring-controlledclamp B comprising the rod n, journaled in said loops, and having ahandle at one end and shoulders n2 at its opposite ends terminating inarms n3 extending toward each other along the upper reinforcing-stripand forming between them the copyinsertion space fm, substantially asdescribed.
